PHP-无法使用复选框删除MySQL行（没有表单）

首先，我想道歉，如果有任何重复的问题问

正如标题所说，我正试图删除用户在

jQuery

帮助下检查的多行。不幸的是，我未能完成这项任务

下面是我正在使用的代码：==>

index.php-->以表格格式显示数据

<?php
require_once '../../Classes/class.Validation.php';
$validate = new Validation('ecommerce');
$qu = "SELECT ProdCode, ProdName, ProdDescription, ProdRate, ProdTotalQuantity, ProdAvailability FROM products";
$validate->Query($qu);
if ($validate->NumRows()) {
?>
    <div class="container-fluid">
        <div class="table-responsive">
            <table border="1" class="table table-bordered table-striped">
                <thead>
                    <tr>
                        <th><input type="checkbox" id="all" name="deletePrd[]"></th>
                        <th>Prod-Image</th>
                        <th>Prod-Code</th>

替换

data: count_checked.serialize(),

在没有表单的情况下，要么使用ajax onClick发布数据，要么在URL上以逗号分隔作为查询参数传递多个选定ID，我该怎么做？问题是，我是这方面的初学者请注意：请注意：@GBD我在使用第二个链接中提供的答案时，将NULL作为输出。。现在检查更新的jQuery部件。。

$("a[id='del']").click(function() {
        var count_checked = $("[name='deletePrd[]']:checked").length;
        var checkedCode = $("[name='deletePrd[]']:checked").attr("id");
        if(count_checked == 0) {
            alert("Please select product(s) to delete.");
            return false;
        }
        if(count_checked == 1) {
            //return confirm("Are you sure you want to delete this product ?");
            if (confirm('Are you sure you want to delete this product ?')) {
                $("a[id='del']").attr("href", "http://www.example.com/ECommerce/ActionFiles/DeleteProduct.php?prdCode=" + checkedCode);
            }
        } else if(count_checked > 1) {
            if (confirm('Are you sure you want to delete the selected products ?')) {
                $("a[id='del']").attr("href", "http://www.example.com/ECommerce/ActionFiles/DeletedSelectedProducts.php");
